It seems like you've tried out self-learning and are frustrated with your lack of progress. I recommend taking a few classes. You can do this a few ways - from a friend who knows how to play, or from a guitar store.
Sometimes the friend route is not the best, cause he/she wouldn't know the best way to teach you, but if you really can't afford classes (or are just cheap, like me

), go for it. I've tried teaching a few people (all never played before -real beginners) and only one person really learnt anything useful from me - maybe I'm just a bad teacher!
A friend is also the best way to learn about guitar maintenance, etc, cause I know that most places won't teach you that. You can pick up the lingo, and learn things like how to change strings, where to get the best deal on fixing stuff, etc.
Otherwise, go for a month or two of classes. I did when i started and found that after three months (and about $400 later), I could play most of the simple chords and songs, and was better off learning on my own. All I needed was a foundation on what/how to learn. Be careful about where you learn though - it's sad to say but some teachers at guitar stores don't really know how to teach. I speak from experience. Sometimes they make you buy expensive books and seem more intent on making you buy a new guitar from them than teaching you how to play properly (I won't name the store cause they might have changed now).
LYN has a sticky thread about this, so check it out before you go to any stores. A few months of solid, real guitar classes and you will see leaps in your playing ability and confidence. You can decide then if you want to stick to it, or if you think you can start learning on your own.
Remember that learning to play the guitar will take lots of patience and practice. You never really finish learning. You just keep picking up new things/techniques all the time. And there are tons of songs to learn, so you'll never get bored. Good luck!
